Two experiments were conducted to compare broiler chicken responses to methionine and betaine supplements when fed diets with low protein and relatively high metabolizable energy levels (17%, 3.3 kcal/g) or moderate protein and lower metabolizable energy levels (24%, 3.0 kcal/g), resulting in different levels of carcass fat. In Experiment 1, the basal diets were formulated with corn, soybean me...

This study aimed to analyse changes in the profile of long-chain fatty acids ruminal fluid cows during vitro fermentation, using different proportions maize DDGS (distillers dried grains with solubles) as a substrate. The serum bottles were filled 1 g concentrate feed (C), which consisted cereal middlings, postextraction rapeseed meal, and soybean meal. Substrates I, II, III contained same ingr...

Invasive non-native species frequently occur in very high densities. When such invaders present an economic or ecological nuisance, this biomass is typically removed and landfill is the most common destination, which is undesirable from both an economic and ecological perspective. The zebra mussel, Dreissena polymorpha, has invaded large parts of Europe and North America, and is routinely remov...

Poultry farmers and birds are exposed to poultry dust which is a byproduct of commercial production. It increases the chances developing serious respiratory conditions. Adult male Wistar rats were used in this study due their stable hormonal status investigate effect (PM10) on biochemical, haematological histopathological parameters animals. The samples collected from 9 farms Edo State. Indoor ...

ruary-March; Experiment 2, April-May; and Experiment 3, June-July. Birds received a corn-soybean meal starter (0.68 kg/bird; 22% CP, 3087 kcal/kg ME), grower (1.36 kg/bird; 20% CP, 3131 kcal/kg ME), and finisher (c.a. 2.27 kg/bird; 17.5% CP, 3197 kcal/kg ME) to 42 days of age. Treatments were control (CON); Poultry Litter Treatment (PLT), Poultry Guard (PG) or 50:50 All-Clear:PLT (ACPLT) at 100...

Two-pot experiments with ryegrass and wheat plants were conducted in a Cambic Arenosol to test the reliability of N fate predicted by incubation experiments previously performed, with the same soil, to assess potentially mineralizable nitrogen from six organic wastes (municipal solid waste compost, secondary pulp mill sludge, horn meal, poultry manure, solid phase from pig slurry and composted ...

Approximately 25 to 40% of the DM in premium dog diets is animal by-product. However, limited information is available regarding the composition and digestibility of these by-products, especially small intestinal digestibility. The effects of raw and rendered animal by-products incorporated into dog diets on nutrient digestion at the ileum and in the total tract were studied in this experiment....

Livestock, particularly ruminants, can eat a wider range of biomass than humans. In the drive for greater efficiency, intensive systems of livestock production have evolved to compete with humans for high-energy crops such as cereals. Feeds consumed by livestock were analysed in terms of the quantities used and efficiency of conversion of grassland, human-edible ('edible') crops and crop by-pro...
